I. Working Principle of X-Ray counting Machine
X-rays are electromagnetic waves with extremely short wavelengths and strong penetrating capabilities, capable of passing
through most non-metallic materials. The X-ray component placement machine utilizes this property to achieve "transmission-
style" imaging of electronic components.
The basic principle is similar to the X-ray machine used in hospitals for bone examinations: without the need to unpack the
components, the X-ray beam can penetrate the roll holder, packaging film, and even plastic boxes to image their internal structures.
After image acquisition, the system automatically determines the quantity of components through image recognition algorithms
(typically based on grayscale contrast and edge detection).
This process does not rely on manual unpacking or physical contact at all, hence it is referred to as "non-contact counting.".
2. What is the process for non-contact counting?
Although the software interfaces of each equipment manufacturer vary slightly, the workflow of the X-ray component placement
machine is roughly as follows:
Loading: Place the material tray or tape to be counted onto the machine's scanning platform without unpacking.
Set parameters: Input the necessary parameters such as component type, specifications, and tape spacing. Some equipment
supports automatic recognition.
X-ray scanning: After the machine is activated, the X-ray source emits penetrating waves that pass through the packaging material
and scan the components.
Image Imaging and Recognition: The receiver captures the penetrated image, and the system automatically performs image
processing and recognition.
Automatic counting: The system determines the precise quantity by calculating the contour of the device or identifying the
particle distribution in each pixel.
